摘要
The rapid progress of high-performance microelectronic devices underscores the urgent necessity to develop materials possessing superior thermal conductivity for effectively dissipating heat in cutting-edge electronics. Boron nitride nanosheets (BNNSs) have garnered significant attention due to their exceptional thermal conductivity, combined with electrical insulation and low thermal expansion coefficient, offering a promising solution to heat-related challenges in electronic devices. While BNNSs share some common thermal behaviors with other two-dimensional (2D) materials, they also exhibit unique characteristics. For instance, BNNSs exhibit larger isotope disorders compared to graphene, yet their isotope enhancement in thermal conductivity is lower than that of their carbon counterpart. This review provides an overview of the thermal transport properties and mechanisms of BNNSs explored over the past decade, beginning with a brief introduction to the basic of thermal conductivity. It then delves into the thermal transport mechanisms in BNNSs, highlighting factors impacting the in-plane thermal conductivity of BNNSs, as well as the cross-plane thermal conductivity and the factors influencing it. Finally, the review discusses challenges associated with BNNS thermal conductivity measurement and outlines potential future research avenues.
